FIELD

This application relates to sharing digital information between mobiledevices.

BACKGROUND

Devices may use a variety of wireless protocols to communicate with oneanother, such as IEEE 801.11 (Wi-Fi) or Bluetooth. For example, awireless gateway may be wirelessly connected to mobile devices such assmartphones, tablet computers, laptop computers, and the like, and mayprovide a connection between such devices and the Internet or otherwired network to which the wireless gateway is connected. But dependingon the particular devices, a user may need to have a certain amount oftechnical expertise to initially establish a connection between thedevices. For example, a wireless gateway using IEEE 802.11 may beassigned one or more extended service set identifiers, or ESSIDs(sometimes referred to as SSIDs), each of which may be a sequence ofnumbers or letters that identifies that wireless gateway to otherdevices, preferably uniquely. The wireless gateway may broadcast one ormore of its ESSIDs so as to alert other devices to the wirelessgateway's presence on the network. The wireless gateway also may haveone or more access credentials, such as a login and password, or anencryption key, which may be associated with a particular one of theESSIDs. The wireless gateway may be programmed to permit devices toconnect that (1) transmit the proper ESSID to the wireless gateway, and(2) transmit the proper credential to the wireless gateway. Technicallysavvy users within Wi-Fi range readily may be able to obtain the ESSIDof a wireless gateway and the proper credential, and to suitablyconfigure a mobile device to wirelessly transmit that ESSID andcredential to the wireless gateway so as to connect to the wirelessgateway. But users outside of the wireless gateway's Wi-Fi range maylack sufficient technical savvy to connect their mobile device to thegateway via the Internet using the gateway's wide area network (WAN)internet protocol (IP) address, and even if they could connect to thegateway they may not be able to communicate meaningfully with it.

Moreover, different mobile devices connected to a given wireless gatewaymay not be able to share information readily with one another. Atechnically savvy user may be able to set up a local media server basedon Windows™ Media Player (Microsoft Corporation, Redmond Wash.), or theHome Sharing feature within iTunes™ (Apple Inc., Cupertino Calif.), orother commercially available software on a personal computer that isconnected to the wireless gateway. Mobile devices that are directlyconnected to the gateway via Wi-Fi and having the proper softwarethereon then may access digital media, such as photographs or videos,stored on the local media server. But devices that are not directlyconnected to the wireless gateway may not access the digital media.So-called “cloud” based services also are commercially available thatpermit mobile devices to share digital media over the Internet,typically providing a fixed amount of storage space, sometimes inexchange for a fee. For example, iCloud™ (Apple Inc., Cupertino Calif.)is a service that stores a user's digital media such as music, photos,apps, documents, books, mail, notes, reminders, contacts, and calendarson a remote server. The remote server then pushes such media to any ofthe user's enrolled mobile devices over Wi-Fi or over a cellular datanetwork such as 3G or 4G, without the need to connect to a particulargateway or local computer.

Certain aspects of cloud based services such as iCloud™ may limit theirusefulness to certain users, and thus may limit their adoption. Forexample, because a cloud based service may store the personalinformation of millions of users within a central or distributeddatabase, some users may be concerned about the privacy of theirinformation. Moreover, such a database may represent a particularlyappealing target for hackers, because of the potential to access theinformation of so many users simultaneously. Additionally, the amount ofstorage space available to the user typically is fixed and relativelylow, with additional increments of storage space available at anincreasing cost. For example, the iCloud™ service presently provides theuser with 5 GB of free storage, and charges a fee for additionalstorage. The cloud based service also may limit the types of informationthat the user may store.

Thus, what is needed is a system and method to facilitate the sharing ofdigital information between mobile devices.

DETAILED DESCRIPTION

Overview

Exemplary embodiments of the present invention provide embeddeddevice-based systems and methods for establishing wireless clouds forsharing digital information between mobile devices of friends andfamily. More specifically, embodiments of the present invention mayprovide an embedded device for use in a home networking environment,e.g., that is configured to connect to the Internet via an Internetservice provider (ISP) and to connect to mobile devices via Wi-Fi, e.g.,in a local area network (LAN) environment, and also that is configuredto connect to remote mobile devices via a wide area network (WAN)environment. The present embedded device also includes different logicalmodules therein that are configured to establish a “family cloud” thatpermits only selected mobile devices—such as those of friends andfamily—to wirelessly share digital information, such as digital media,with one another via the LAN or WAN environment. In particular, thepresent embedded device may enroll a first mobile device as an “admin”device associated with the embedded device, and may permit that deviceto manage the cloud and to invite other selected mobile devices toenroll to the family cloud, e.g., to be associated with the embeddeddevice. However, such selected mobile devices need not necessarily bewithin Wi-Fi range of the embedded device to be invited or to enroll tothe family cloud. Instead, the invitation may be sent from the admindevice using the device's native email application and transmitted tothe selected mobile device via the Internet or via the LAN environmentif local, and opened and accepted at the selected mobile device,wherever that mobile device may be. Preferably, the invitation enrollsthe mobile device into the family cloud without requiring any technicalknowledge on the user's part, e.g., without requiring knowledge of theembedded device's wide area network (WAN) IP address, ESSID, orcredential, and indeed without requiring the mobile device ever to bewithin Wi-Fi range of the embedded device. For example, a dedicatedapplication or “app” for the mobile devices' use in enrolling to andutilizing the family cloud in a user-friendly manner may be downloadedfrom an online store, such as iTunes™ (Apple Inc., Cupertino, Calif.),Google™ Play (Google Inc., Mountain View Calif.), Windows™ Phone Store(Microsoft Corporation, Redmond Wash.), or BlackBerry™ World(Blackberry, Waterloo, Ontario, Canada).

Mobile devices enrolled to the family cloud, e.g., associated with theembedded device, may share digital information with one another in astreamlined, user-friendly manner via the LAN or WAN environment. Forexample, the mobile device may upload digital information to theembedded device either via Wi-Fi (LAN) or via a cellular data networksuch as 3G or 4G (WAN). The embedded device then may send a pushnotification of that digital information to the other enrolled mobiledevices using a Global Push Notification Server, such as maintained byApple Inc. or Google Inc., that is connected to the Internet, or using athird-party push notification service that may utilize such a GlobalPush Notification Server; of course, if any enrolled mobile devices arewithin the LAN environment of the embedded device, then the embeddeddevice instead may notify such mobile devices of the digital informationusing a direct message, rather than a push notification. Accordingly,the mobile devices may receive notifications of the digital information,wherever those mobile devices may be. Preferably, the embedded devicealso includes an internal storage device or is configured to connect toan external storage device, such as a hard drive, in which the digitalinformation may be stored and later retrieved as desired. As such, theamount of available storage space and the type of information that maybe stored therein may be determined by the size of the storage devicethat the user is willing or able to purchase; for example, at present,external hard drives having 1 TB or more of storage space arecommercially available for $100 or less. Such an internal or externalstorage device may not present a particularly desirable target forhacking, because it only may contain the digital information of a fewusers. In comparison, the above-mentioned cloud based services may limitthe user to only a few GB of storage space unless additional fees arepaid to obtain incrementally more space, and may present a far moredesirable target for hacking because the digital information of millionsof users may be stored together.

Additionally, in some embodiments, multiple embedded devices may benetworked together over the Internet, and the family clouds of thoseembedded devices may be merged together to provide a “merged” cloud inwhich digital information may be shared between multiple mobile devices.Such a merged cloud may facilitate communication between the multipledevices in a streamlined, user-friendly manner. As described in greaterdetail below, the embedded devices may store and utilize different rulesfor sharing and synchronizing digital information between the otherembedded devices and the mobile devices, for example so as to quicklydistribute higher priority information, and to efficiently andnon-invasively distribute lower priority information.

Note that in preferred embodiments, the present embedded devices arewireless gateways, which are a stand-alone piece of equipment whoseprimary function is to route network traffic between a local areanetwork (LAN) and a wide area network (WAN) such as the Internet, usinga modem; that is, a wireless gateway includes the functionality both ofa router and a modem. As is known in the art, gateways are embeddedsystems that have limited resources such as system memory, storage, andcomputing power. The logical modules within the present embeddeddevices, e.g., wireless gateways, preferably provide the “family” cloudfunctionality without requiring significant modifications to thephysical parameters of the gateway, e.g., without requiringsignificantly more system memory, storage, or computing power thantypically is provided in an embedded device, e.g., gateway. Inparticular, the present embedded devices, e.g., wireless gateways,preferably are not part of a server, and indeed need not even be coupledto a personal computer. As is known in the art, the primary function ofa server is to provide different kinds of applications or services toclients. Although technically savvy users may set up local media serverson a home personal computer that is connected to a gateway, andcloud-based services may store digital media on a remote server, thepresent embedded devices, e.g., wireless gateways may obviate the needto purchase, set up, or to utilize a local or remote server in order toestablish a wireless cloud to share digital information between mobiledevices. Other exemplary embedded devices that may be used to sharedigital information between mobile devices may include gateways,routers, wireless routers, media players, wireless media players, accesspoints, wireless access points, network access storage (NAS) devices,thumb drives, and embedded servers.

A first embodiment of an embedded device-based system for providing afamily cloud for sharing digital information between mobile devices, andmethods and signaling protocols associated with same, will be described.Then, alternative systems, methods, and signaling protocols will bedescribed.

Embedded Device-Based System

FIG. 1 illustrates embedded device-based system 100 for providing afamily cloud for sharing digital information between mobile devices,according to some embodiments of the present invention. System 100includes embedded device 110, admin mobile device A 120, and a pluralityof family mobile devices B . . . N 130-B . . . 130-N. Although certainfunctionalities of system 100 are primarily described below withreference to family device B 130-B, it should be understood that theother family devices may operate analogously to family device B.Furthermore, note that family devices B . . . N 130-B . . . 130-N neednot necessarily be used or owned by a family member of the user who usesor owns admin device A 120, but instead may be owned by any friend,acquaintance, colleague, associate, or the like, or the user who uses orowns admin device A 120—that is, any individual or entity who that userwishes to share access to the family cloud established by embeddeddevice 110.

Embedded device 110 may include processor 111, non-volatilecomputer-readable medium or memory 112, a Wi-Fi transceiver (notspecifically illustrated) via which the embedded device may wirelesslyconnect to admin device A 120 and optionally also family device B, afirst input/output (I/O) port (not specifically illustrated) via whichthe embedded device may connect to the Internet, optionally via internetservice provider (ISP) 170, and a second I/O port (not specificallyillustrated) via which the embedded device may connect to an externalstorage device 171; alternatively, the embedded device may include aninternal storage device (not illustrated). For example, in someembodiments the first I/O port includes a modem, such as an analogmodem, cable modem, long-term evolution (LTE) modem, fiber modem,digital subscriber line (DSL) modem, or very-high-bit-rate digitalsubscriber line (VDSL) modem, that facilitates connection betweenembedded device 110 and ISP 170 and then to the Internet via appropriatecabling. In other embodiments, embedded device 110 is an embedded devicelacking modem functionality and instead is configured to connect to theInternet through a modem, e.g., via the first I/O port and a modem andEthernet cable (not illustrated). The second I/O port may include a USBport, USB 2.0 port, USB 3.0 port, firewire port, or any other suitableport via which digital information may be transmitted to externalstorage device 171, e.g., an external hard drive based on FLASH, RAM,ROM, EPROM, EEPROM, or a magnetic or optical disk or tape. In oneillustrative embodiment, storage device 171 includes a Wi-Fi orBluetooth transceiver and the second I/O port of embedded device 110includes the Wi-Fi transceiver (not illustrated) or a Bluetoothtransceiver via which embedded device 110 may wirelessly communicatewith storage device 171. As noted above, the embedded devicealternatively may include an internal storage device such as a harddrive or flash drive. In one illustrative embodiment, the embeddeddevice includes both an internal storage device and a second I/O portvia which the embedded device may connect to an external storage device171.

Preferably, embedded device 110 is configured to allow mobile devicesconnected thereto to access the Internet via the Wi-Fi transceiver andport first I/O port upon exchange of suitable credentials, such as alogin and password or an encryption key. For example, the Wi-Fitransceiver may be configured to receive radio frequency (RF) signalsfrom mobile devices such as admin device 120, and to communicate adigital representation of such signals to processor 111; and to receivedigital signals from processor 111 and to transmit RF representations ofthose signals to mobile devices such as admin device 120. The first I/Oport may be configured to receive digital signals from the Internet, andto communicate those signals to processor 111; and to transmit digitalsignals from processor 111 to the Internet. Computer-readable medium 112of embedded device 110 may include an internal or external memorydevice, such as FLASH, RAM, ROM, EPROM, EEPROM, or a magnetic or opticaldisk or tape.

Computer-readable medium 112 of embedded device 110 is configured tostore family cloud application 113, which includes enrollment module114, sharing module 115, push module 116, IP address update module 117,rules 1 . . . M 118, and identifiers A, B, . . . N 119. As described ingreater detail below with reference to FIGS. 2 and 3, enrollment module114 is configured to cause processor 111 to enroll admin device A 120and family devices B . . . N 130-B . . . 130-N to a family cloud, e.g.,to associate such devices with embedded device 110, via which thedevices may wirelessly share digital information with one another. Asdescribed in greater detail below with reference to FIG. 4, sharingmodule 115 is configured to cause processor 111 to receive digitalinformation from one of admin device A 120 and family devices B . . . N130-B . . . 130-N and to cause push module 116 to push a notification ofthe digital information to the others of such devices. In oneillustrative embodiment, push module 116 pushes such a notification viathe first I/O port and via Global Push Notification Server (GPNS) 180connected to the Internet, optionally via a third-party pushnotification service. However, note that if any of admin device A 120 orfamily devices B . . . N 130-B . . . 130-N are in the LAN environment ofembedded device 110, then push module 116 instead may notify such mobiledevices of the digital information using a direct message, rather than apush notification.

As described in greater detail below with reference to FIG. 6, IPaddress update module 117 is configured to cause processor 111 to sendto admin device A 120 and family devices B . . . N 130-B . . . 130-N anew WAN IP address for embedded device 110, e.g., if ISP 170 assigns anew WAN IP address to the embedded device. In one illustrativeembodiment, IP address update module 117 causes push module 116 to pushthe new WAN IP address via the first I/O port and via GPNS 180 connectedto the Internet; alternatively, if any of admin device A 120 or familydevices B . . . N 130-B . . . 130-N are in the LAN environment ofembedded device 110, then push module 116 instead may notify such mobiledevices of the new WAN IP address using a direct message, rather than apush notification. As described in greater detail below with referenceto FIGS. 5A-5D, the various modules of family cloud application 113 mayfacilitate or control the sharing of digital information between admindevice A 120 and family devices B . . . N 130-B . . . 130-N based on oneor more rules 1 . . . M 118.

Computer-readable medium 112 also stores identifiers 119 A, B, . . . Nfor admin device A 120 and family devices B . . . N 130-B . . . 130-N,e.g., one or more notification receipt identifiers (NRID), internationalmobile station equipment identity (IMEI) numbers, mobile equipmentidentifiers (MEID), or electronic serial numbers (ESN). Identifiers 119may be stored within computer-readable medium 112 during enrollment ofadmin device A and family devices B . . . N 130-B . . . 130-N usingenrollment module 114, and may be used by push module 116 to pushdigital information or a new WAN IP address of embedded device 110 toadmin device A 120 and family devices B . . . N 130-B . . . 130-N. Inthe illustrated embodiment, identifiers 119 A, B, . . . N are storedwithin family cloud application 113, but it should be understood thatthe identifiers need not necessarily be stored within the family cloudapplication so long as they may be accessed by such application.

As illustrated in FIG. 1, computer-readable medium 112 preferablyfurther stores new application (“app”) module 150, an embedded devicecomponent of a first new application (“embedded device comp-1”) 151, andan embedded device component of a second new application (“embeddeddevice comp-2”) 152. As described in greater detail herein, new appmodule 150 may facilitate loading of executable modules or components ofnew applications onto embedded device 110, which modules or componentsmay facilitate sharing of digital information with mobile devices 120and 130 B . . . N. In the illustrated embodiment, new application module150 is part of family cloud application 113.

Admin device A 120 includes processor 121, computer-readable medium ormemory 122, display device 129, user input device 129′, a Wi-Fitransceiver (not illustrated), and a cellular data transceiver, e.g., a3G or 4G transceiver (not illustrated). Computer-readable medium 122 ofadmin device A 120 may include an internal or external memory device,such as FLASH, RAM, ROM, EPROM, EEPROM, or a magnetic or optical disk ortape. Computer-readable medium 122 of admin device A 120 is configuredto store admin application (“admin app”) 123. Admin application 123includes enrollment module 124 configured to cause processor 121 toenroll admin device A 120 to the family cloud of embedded device 110,e.g., to become associated with the embedded device, preferably byinteracting with enrollment module 114 of the embedded device such asdescribed below with reference to FIG. 2. Admin application 123 alsoincludes invitation module 125 via which family devices B . . . N 130-B. . . 130-N may be invited to enroll to the family cloud of embeddeddevice 110, e.g., to become associated with the embedded device,preferably by interacting with enrollment module 114 of the embeddeddevice such as described below with reference to FIG. 3. Adminapplication 123 further includes sharing module 126 configured to causeprocessor 121 to receive digital information and to transmit thatdigital information to embedded device 110 for distribution to familydevices B . . . N 130-B . . . 130-N by interacting with sharing module115 and push module 116 of the embedded device such as described belowwith reference to FIG. 4. Computer-readable medium 122 furtherpreferably stores new application module (“new app module”) 140 and amobile device component of a first new application (“mobile devicecomponent-1”) 141, which as described herein may further facilitate theimplementation of new applications for sharing information betweenembedded device 110 and admin device A 120. In the illustratedembodiment, new application module 140 is part of admin application 123.

As noted above, preferably admin application 123 may be downloaded froman online app store. For example, a dedicated application or “app” forthe mobile devices' use in enrolling to and utilizing the family cloudin a user-friendly manner may be downloaded from an online store, suchas iTunes™, Google™ Play, Windows™ Phone Store, or BlackBerry™ World. Inone illustrative embodiment, embedded device 110 includes printedinstructions that describe how to download admin application 123, orgenerates a message to admin device A 120 that contains digitalinstructions via which the user may download admin application 123.Computer-readable medium 122 further may store a native emailapplication 127 and the WAN IP address 128 of embedded device 110, whichenrollment module 124 may receive from embedded device 110 whenconnecting via Wi-Fi to the embedded device during enrollment to thefamily cloud.

Family device B 130-B includes processor 131, computer-readable mediumor memory 132, display device 139, user input device 139′, a Wi-Fitransceiver (not illustrated), and a cellular data transceiver, e.g., a3G or 4G transceiver (not illustrated). Computer-readable medium 132 offamily device B 130-B may include an internal or external memory device,such as FLASH, RAM, ROM, EPROM, EEPROM, or a magnetic or optical disk ortape. Computer-readable medium 132 of family device B 130-B isconfigured to store family application (“family app”) 133. Familyapplication 133 includes response module 135 configured to causeprocessor 131 to enroll family device B 130-B to the family cloud ofembedded device 110 responsive to an invitation sent from invitationmodule 125 of admin device A 125, preferably by interacting withenrollment module 114 of the embedded device such as described belowwith reference to FIG. 3. Family application 133 further includessharing module 136 configured to cause processor 131 to receive digitalinformation and to transmit that digital information to embedded device110 for distribution to admin device A 120 and to others of familydevices C . . . N 130-C . . . 130-N by interacting with push module 116of the embedded device such as described below with reference to FIG. 4.Computer-readable medium 132 further preferably includes new applicationmodule (“new app module”) 160 and a mobile device component of a secondnew application (“mobile device component-2”) 161, which as describedherein may further facilitate the implementation of new applications forsharing information between embedded device 110 and family device B130-B. In the illustrated embodiment, new application module 160 is partof family application 133.

As noted above, preferably family application 133 may be downloaded froman online app store such as iTunes™, Google™ Play, Windows™ Phone Store,or BlackBerry™ World. In one illustrative embodiment, the invitationsent from invitation module 125 contains a link that causes familyapplication 133 to be downloaded to and installed on family device B130-B, thus reducing the burden on the owner of family device B toidentify, download, and install the family application. Additionally,note that family application 133 and admin application 123 may bedifferent functionalities of the same application. Computer-readablemedium further may store a native email application 137 and the WAN IPaddress 138 of embedded device 110, which response module 135 mayreceive from embedded device 110 during enrollment to the family cloud.As noted above, family devices C . . . N 130-C . . . 130-N may beconfigured analogously to family device B 130-B.

In many regards, embedded device 110, admin device A 120, and familydevices B . . . N 130-B . . . N may be otherwise “off-the-shelf,”commercially available components that are modified so as to includefeatures that facilitate establishing, enrolling in, and participatingin a family cloud. For example, admin device A 120 and family devices B. . . N 130-B . . . 130-N each may be a commercially availablesmartphone, such as an iPhone, Android-based phone, BlackBerry, orWindows-based phone, or another suitable device that may wirelesslyconnect to an embedded device, such as a laptop computer, personaldigital assistant, iPad, tablet computer, netbook, and the like. Admindevice A 120 and family devices B . . . N 130-B . . . 130-N need notnecessarily be of the same type as one another, e.g., may include amixture of iPhone or iPad devices, Android-based devices, BlackBerrydevices, or Windows-based devices. However, in the illustratedembodiment, admin device A 120 is configured to store incomputer-readable medium 122 admin application 123 and WAN IP address128 for use in enrolling in and participating in the family cloud, andfamily devices B . . . N 130-B . . . 130-N respectively are configuredto store in computer-readable medium family application 133 and WAN IPaddress 138 for use in enrolling in and participating in the familycloud.

In one exemplary embodiment, embedded device 110 may contain analogouscomponents as a commercially available fiber optic modem gateway, a DSLor VDSL modem gateway, analog modem gateway, cable modem gateway, fibermodem gateway, LTE modem gateway, or any other suitable gateway that maybe connected to the Internet and may provide a wireless connectionbetween a mobile device and the Internet. However, in the illustratedembodiment, embedded device 110 is further configured to store incomputer-readable medium 112 family cloud application 113 and mobiledevice identifiers 119 for use in sharing digital information betweenadmin device A 120 and family devices B . . . N 130-B . . . 130-N, suchas described below with reference to FIG. 4. Additionally, embeddeddevice 110 is configured to communicate with external storage device171, the capacity of which may be defined by the user and which may bereplaced or augmented at relatively low cost, or an internal storagedevice, which optionally may be made replaceable or upgradable by theuser or by a certified technician.

Moreover, so as to support multiple types of digital information andmultiple types of interactions with admin device A 120 and familydevices B . . . N 130-B . . . 130-N, embedded device 110 preferably ismodified so as to support runtime executable software installation,e.g., so as to include new application module 150 which facilitates thedownloading of embedded device components or modules of one or more newapplications, e.g., “embedded device comp-1” of a first new applicationand “embedded device comp-2” of a second new application. As is known inthe art, existing embedded software on a gateway may not necessarilysupport user space executable module upload or installation—that is, maynot necessarily support installation of a new application. Although opensource code is available that supports user space executable moduleupload, such code may only permit a single authority—that is, a singlemobile device—to upload executable modules. Such a limitation isundesirable because a family cloud preferably would permit any deviceenrolled within the cloud to upload an executable module, and thuspermit any such mobile device to install on the embedded device a newapplication having a component or module that interacts with acorresponding component or module on the mobile device. Also, such codefurther may require that authority to maintain the connection to theembedded device at all times, e.g., to a Linux kernel within a gateway,in order to maintain the executable module in an open state. Forexample, if a mobile device connects to a previously known gateway, theembedded software within the gateway may assign logical input/outputdevices for the mobile device. If the logical input/output devices arenot detected, for example if the mobile device goes into sleep mode,then the software may close the executable module. Preferably, familycloud application 113 is configured to permit any authority—that is, anymobile device that has enrolled to the family cloud—to upload executableapplication components or modules to embedded device 110, and tomaintain the components or modules in an active state even in theabsence of detectable logical input/output devices so that each mobiledevice may interact with the components or modules.

Additionally, in typical interactions between a previously known cloudserver and a client thereof, e.g., a mobile device, the server and theclient may share similar computing environments as one another, e.g.,may both be based in the same or a related computer language as oneanother, which may simplify the development of interactive applicationsthat run on both the server and the client. However, within system 100,the computing environment of embedded device 110 may be significantlydifferent than that of admin device A 120 and family devices B . . . N130-B . . . 130-N, which may complicate the development of interactiveapplications having components or modules that respectively run on boththe embedded device and the mobile devices. For example, the computingenvironment of embedded device 110 may be based in the C programminglanguage, while the computing environments of admin device A 120 andfamily devices B . . . N 130-B . . . 130-N may be based in JavaScript orErlang.

So as to facilitate interactions therebetween, embedded device 110,admin device A 120, and family devices B . . . N 130-B . . . 130-N mayinclude additional modules that facilitate the installation andexecution of complementary components of a new application on theembedded device and mobile devices, respectively. Specifically, embeddeddevice 110 includes new application module 150, e.g., as part of familycloud application 113; admin device A 120 includes new applicationmodule 140, e.g., as part of admin application 123; and family device B130-B includes new application module 160, e.g., as part of familyapplication 133.

Users respectively may download new applications onto admin device A 120or family device B 130-B, e.g., by downloading the new application froman online app store such as mentioned herein or otherwise known in theart. Preferably, the new application includes two different components:a first component for use at the mobile device, e.g., admin device A120, and a second component for use at the embedded device 110. Duringexecution on admin device A 120 and embedded device 110, the componentsof the new application may share digital information with one another,e.g., the mobile device component 141 may transmit first digitalinformation from the admin device to the embedded device, and theembedded device component 151 may transmit second digital informationfrom the embedded device to the admin device. In one illustrativeembodiment, the mobile device component 141 may be a web based nativeapplication running under the mobile device's hypertext markup language(HTML) and JavaScript environment and configured to interact with theembedded device component-1 151, and the second component 151 may be anon-SQL database “object”-based application configured to interact withmobile device component 141. Analogously, embedded device 110 mayinclude different embedded device components for different newapplications. For example, a second new application downloaded ontofamily device B 130-B may include a mobile device component 161, e.g.,an HTML and JavaScript base application, and an embedded devicecomponent-2 152 configured to interact with the mobile device component161, e.g., a non-SQL database object-based application.

Indeed, with such an architecture, the admin application 123 and familyapplication 133 may have flexible web-application based graphical userinterfaces (GUIs), and at the same time may leverage the current mobiledevice application open platform development environment. Anotherbenefit of such an application design architecture is that the newapplication module 140 or 160 may push the embedded device component 151or 152 of the new application to embedded device 110 automaticallywithout the need for user intervention, for example so long as the userkeeps an “automatic upload” default within admin application 123 orfamily application 133; or alternatively the new application module 150may request the embedded device component of the new application fromnew application module 140 or 160, e.g., responsive to detection of thenew application at the mobile device; or alternatively the newapplication module 150 may download the embedded device component of thenew application via the Internet, e.g., responsive to detection of thenew application at the mobile device. Further details of downloading andexecuting mobile and embedded device components of new applications areprovided further below with reference to FIGS. 11A-11B.

Additionally, it should be understood that new application module 140optionally may be suitably implemented within family cloud application113, and similarly new application modules 150 and 160 optionally may besuitably implemented within admin application 123 and family application133; alternatively, such new application modules 140, 150, and 160 maybe implemented within other applications, or even as stand-aloneapplications. That is, the use of new application modules, and the usethereof to obtain and execute mobile device and embedded devicecomponents of new applications that may be selected by the user, may beused to facilitate family clouds, but is not limited to implementationin the context of family clouds, although family clouds may particularlybenefit from such modules and components.

Methods of Enrolling Mobile Devices to Family Cloud

FIGS. 2 and 3 illustrate steps executed by mobile devices and anembedded device such as a embedded device during exemplary methods forenrolling the mobile device to a family cloud, e.g., for associatingmobile devices with the embedded device. Specifically, FIG. 2illustrates steps in an exemplary method 200 for enrolling an admindevice, e.g., for enrolling admin device A 120 to the family cloud ofembedded device 110 illustrated in FIG. 1, while FIG. 3 illustratessteps in an exemplary method 300 for enrolling a family device, e.g.,for separately enrolling each of family devices B . . . N 130-B . . .130-N illustrated in FIG. 1.

For enrolling an admin device, on the mobile device side, method 200illustrated in FIG. 2 begins with an admin device A downloading an adminapplication (“app”) from an online app store (step 211). For example,admin device A 120 illustrated in FIG. 1 may connect to the app storevia a Wi-Fi connection to embedded device 110 and via ISP 170 to theInternet; via a Wi-Fi connection to a different embedded device andthrough the Internet; or through a cellular data connection such as 3Gor 4G and through the Internet. Exemplary online app stores arementioned above and known in the art. Embedded device 110 may be shippedto or otherwise provided to the user of admin device A 120 with a set ofprinted or electronic directions for explaining to the user the familycloud functionality of embedded device 110 and directing them todifferent online app stores via which the admin application may bedownloaded to manage the family cloud. In one illustrative embodiment,the admin application is specifically configured only for use on admindevices for use in managing the family cloud of a given embedded device.Alternatively, the admin application for use by admin devices and thefamily application (described in greater detail below) for use by familydevices may one and the same, but only admin devices may use certainfeatures of that application to manage the family cloud. The use of theterms “admin application” and “family application” are intended toencompass both alternatives.

Continuing on the mobile device side, method 200 continues with admindevice A starting the admin application, which then receives anidentifier for admin device A (step 212). In one illustrativeembodiment, upon starting, the admin application is assigned anidentifier such as an NRID by a Global Push Notification Server (GPNS)or a third party push notification service and then receives and storesthe identifier.

On the embedded device side, method 200 illustrated in FIG. 2 includesstarting a family cloud application (step 221). In one example, embeddeddevice 110 may start family cloud application 113 stored incomputer-readable medium 112 when the embedded device is turned on andmay maintain that application in an active state at any time that theembedded device is on.

On the mobile device side, method 200 illustrated in FIG. 2 furtherincludes the admin device A connecting to the embedded device via Wi-Fiand, within the admin application, transmitting the identifier (ID) foradmin device A to the embedded device (step 213). In some circumstances,admin device A may already be connected to the embedded device, e.g., soas to download the admin application. In other circumstances, admindevice A may have downloaded the admin application at an earlier time orvia a different connection to the Internet. For example, enrollmentmodule 124 of admin application 123 illustrated within FIG. 1 preferablyincludes a GUI that may be displayed on display device 129 of admindevice A 120, and that includes a button prompting the user of to enrollto the family cloud. Upon the user's selection of that button via userinput device 129′, e.g., a touch screen on the admin device A, adminapplication 123 automatically may connect to embedded device 110 and maytransmit the identifier A for admin device A to embedded device 110. TheID for admin device A may include, for example, a notification receiptidentifier (NRID), international mobile station equipment identity(IMEI) number, mobile equipment identifier (MEID), or electronic serialnumber (ESN), or any other identifier via which the admin device A maybe uniquely identified by the embedded device and via which the embeddeddevice may send push notifications directly via a Global PushNotification Server or via a third-party push notification service,e.g., as described in greater detail below with reference to FIG. 4.

On the embedded device side, method 200 illustrated in FIG. 2 furtherincludes permitting access by the admin device A and receiving andstoring the identifier for admin device A (step 222), e.g., respondsappropriately to the admin device A's actions during step 212 so as toestablish bidirectional Wi-Fi communication with admin device A.Enrollment module 114 illustrated in FIG. 1 then may receive and storethe ID for admin device A within computer-readable medium 112 for lateruse by push module 116 to send to admin device A 120 push notificationsof digital information that embedded device 110 receives from othermobile devices enrolled to the family cloud, e.g., family device B130-B, such as described below with reference to FIG. 4.

The embedded device then assigns an access credential to admin device Aand transmits that access credential to admin device A, so that admindevice A may connect to the embedded device via an SSH connection at alater time (step 223). As mentioned above, a mobile device may securelyconnect to an embedded device such as a wireless gateway through asuitable ESSID and by providing an access credential to the gateway toestablish an SSH connection.

In some embodiments, to enroll additional mobile devices, such as any offamily devices B . . . N 130-B . . . 130-N, to the family cloud, thesteps of method 200 illustrated in FIG. 2 may be repeated by that mobiledevice and the embedded device. However, as mentioned above, users otherthan the admin may not be particularly technically savvy, and also maynot be within Wi-Fi range of the embedded device. FIG. 3 illustratesmethod 300 via which the user of the admin device may invite any desireduser—such as a family member, friend, acquaintance, colleague,associate, or the like—to join the family cloud of a embedded device ina manner that does not require technical expertise of that user beyondthe ability to read an email, click on a link therein, and click onbuttons soliciting the user's approval to enroll to the family cloud.

Specifically, method 300 illustrated in FIG. 3 begins on the mobiledevice side in which the admin device A, within the admin application,receives the email address of a family member or other user that theuser of the admin device A wishes to invite to enroll to the familycloud so that they may share digital information with one another viathe embedded device (step 311). For example, invitation module 125within admin application 123 illustrated in FIG. 1 preferably includes aGUI that may be displayed on display device 129 of admin device A 120,and that includes a button prompting the user of that device to inviteothers to enroll to the family cloud. Upon the user's selection of thatbutton via user input device 129′, e.g., a touch screen on the admindevice A, the GUI may display a field prompting the user to type in theemail address of the family member to be invited using input device129′, or an interface permitting the user to select an email addressfrom a contact list or address book stored on admin device A, usinginput device 129′.

Method 300 illustrated in FIG. 3 may continue on the mobile device sideby automatically generating, within the admin application on admindevice A, a message that contains an invitation to enroll to the familycloud and a link to download a family application from an online appstore (step 312). Preferably, the admin application generates such amessage using a native email application within admin device A, and theemail is sent responsive to admin approval (step 312). For example,enrollment module 124 illustrated in FIG. 1 may generate the messagewith link within native email application 127 on admin device A 120, andthe user may approve the message by clicking “send” within the nativeemail application so as to cause the email to be sent to the emailaddress of the user being invited to enroll to the family cloud.Preferably, the email message is relatively easy to understand bynon-technically savvy users, e.g., explains that the family member hasbeen invited to join a family cloud being managed by the user who sentthe email, that family clouds permit family members to share digitalinformation easily with one another, and that the family member mayenroll to the family cloud by clicking the link within the message. Theadmin application may generate the link based on HTML code thatidentifies the name of the family application to be downloaded, and asource from which that application is to be downloaded, e.g., an appstore or a web page. The admin device A then may send the email to theinvited family member via an appropriate communications channel, e.g.,via a Wi-Fi connection to embedded device 110 and via ISP 170 to theInternet; via a Wi-Fi connection to a different embedded device andthrough the Internet; or through a cellular data connection such as 3Gor 4G and through the Internet.

Continuing with the mobile device side of method 300, but at a secondmobile device, specifically family device B, a native email applicationtherein receives the email message with the invitation to enroll in thefamily cloud and the link to download the family application from anonline app store (step 321). For example, native email application 137may display the email to the family member on display device 139, andmay prompt the user to select the link using input device 139′.

Then, responsive to the family member's selection of the link, thefamily application may be downloaded from an online app store onto thefamily device B (step 322). In particular, the HTML code within the linkmay cause a native app store application (not illustrated) on the familydevice B to open and to navigate to an entry for the family app withinthe app store. The family member then may select “install” or otheroption to confirm that the application should be installed.Alternatively, the HTML code within the link may cause a native webbrowser application (not illustrated) to open and to navigate to a webpage that contains different versions of the family application fordifferent operating systems. The family member then may select theproper version for download, or alternatively the web page automaticallymay detect the proper version and cause that version to be downloaded tothe family device B, thus further reducing the burden on the user.

Continuing with the mobile device side of method 300, still at thesecond mobile device, specifically family device B, the familyapplication then automatically generates a reply to the invitationmessage using the native email application on that device (step 323).For example, response module 135 illustrated in FIG. 1 may generate themessage with link within native email application 137 on family device B130-B, and the family member may approve the message by clicking “send”within the native email application so as to cause the email to be sentto the email address of the user who sent the invitation to enroll tothe family cloud. Preferably, the message contains an ID for familydevice B and a link to approve the connection (step 323). The ID forfamily device B may include, for example, a notification receiptidentifier (NRID), international mobile station equipment identity(IMEI) number, mobile equipment identifier (MEID), or electronic serialnumber (ESN), or any other identifier via which the family device B maybe uniquely identified by the embedded device and via which the embeddeddevice may send push notifications via a Global Push Notification Serveror third-party push notification service, e.g., as described in greaterdetail below with reference to FIG. 4. The family application maygenerate the link based on HTML code that identifies the adminapplication or the invitation module therein, for use in completingenrollment of family device B to the family cloud in a later step. Thefamily device B then may send the reply email to the user who sent theinvitation message via an appropriate communications channel, e.g., viaa Wi-Fi connection to embedded device 110 and via ISP 170 to theInternet; via a Wi-Fi connection to a different embedded device andthrough the Internet; or through a cellular data connection such as 3Gor 4G and through the Internet. Note that for step 323, a Wi-Ficonnection to embedded device 110 may be used if family device B is inthe LAN environment.

Continuing with the mobile device side of method 300, admin device Areceives the email message with the ID for family device B and the linkto approve the connection (step 313). For example, native emailapplication 127 may display the email to the family member on displaydevice 129, and may prompt the user to select the link using inputdevice 129′.

Then, responsive to the user's selection of the link, the ID for familydevice B may be transmitted to the embedded device from admin device A(step 314). In particular, the HTML code within the link may causeinvitation module 125 of admin application 123 on admin device A 120 toopen and automatically to transmit the ID for family device B toembedded device 110 illustrated in FIG. 1.

On the embedded device side, method 300 continues with the embeddeddevice, from within the family cloud application, enrolling familydevice B to the family cloud of the embedded device by receiving andstoring the ID for family device B (step 331). For example, enrollmentmodule 114 illustrated in FIG. 1 may receive and store the ID for familydevice B within computer-readable medium 112 for later use by pushmodule 116 to send to family device B 130-B push notifications ofdigital information from other mobile devices enrolled to the familycloud, e.g., admin device A 120, such as described below with referenceto FIG. 4.

Continuing on the embedded device side, so as to confirm the enrollmentof family device B in the family cloud, the family cloud application ofthe embedded device then may send a push notification of the enrollmentin the family cloud to family device B based on the stored ID for deviceB (step 332). For example, enrollment module 114 illustrated in FIG. 1may pass a message indicating successful enrollment to push module 116,with a request to send the message to family device B 130-B. Push module116 then may retrieve the ID 119 for family device B fromcomputer-readable medium 112, and may send the message and the ID forfamily device B to Global Push Notification Service (GPNS) 180 via ISP170 and the Internet, and optionally also via a third-party notificationservice. The GPNS 180 then may send the message in the form of a pushnotification to family device B 130-B. Preferably, the message mayinclude an WAN IP address 138 for embedded device 110, and also an ESSIDand access credential for embedded device 110, which family device B130-B may store in computer-readable medium 132 as shown in FIG. 1 andsubsequently may use to connect to embedded device 110. Optionally, theWAN IP address or ESSID and access credential may be sent in the form ofa link based on HTML code that causes family device B to configureitself appropriately so as to connect to the embedded device based onthe WAN IP address or ESSID and access credential. Alternatively, theWAN IP address or ESSID and access credential for embedded device 110may be sent in the invitation email from admin device A 120 during step312. For example, the HTML code within the link of the invitation emailmay include the WAN IP address or ESSID and access credential of theembedded device and code causing family device B to configure itselfappropriately so as to connect to the embedded device based on the WANIP address or ESSID and access credential. Note that if family device B130-B is in the LAN environment of embedded device 110, then theembedded device may transmit messages directly to the family devicerather than using a Global Push Notification Server or third-party pushnotification service.

Note that although method 300 described above with reference to FIG. 3primarily describes inviting a family member and enrolling that familymember's device in the family cloud, it should be understood that themethod may be used to invite and enroll any individual so desired by theuser of admin device A. Moreover, note that the steps of method 300 neednot necessarily be conditioned on approval by the respective user orfamily member. For example, the emails in step 312 and 323 may be sentautomatically instead of responsive to approval by the user or familymember, or the links within steps 322 or 314 may be automaticallyselected instead of selected by the user or family member. However, itis believed that conditioning such steps on user or family memberactivity may increase security of the family cloud and reduce thelikelihood of enrolling an undesired user to the cloud or of enrollingto an undesired cloud by requiring user or family member confirmationthat the parties are known to one another and that enrollment in theparticular family cloud is desired.

Methods of Sharing Digital Information Using a Family Cloud

Methods of sharing digital information using a family cloud now will bedescribed with reference to FIGS. 4-6.

Specifically, FIG. 4 illustrates steps executed by an embedded deviceand by mobile devices during an exemplary method 400 for sharing digitalinformation between the mobile devices using a family cloud. The mobiledevice side of method 400 begins with admin device A connecting to theembedded device (step 411), and the embedded device side of method 400begins with the embedded device connecting to the admin device A (step421). Such a connection may be made in any suitable manner, such as viaa direct Wi-Fi connection between the mobile device and embedded device110; via a Wi-Fi connection between the mobile device and a differentembedded device and through the Internet based on the WAN IP address ofembedded device 110; or through a connection between the mobile deviceand a cellular data network such as 3G or 4G and through the Internetbased on the WAN IP address of embedded device 110.

On the mobile device side, method 400 continues with receiving userinput selecting digital information to share on the family cloud withinthe admin application on admin device A (step 412). For example, sharingmodule 126 within admin application 123 illustrated in FIG. 1 preferablyincludes a GUI that may be displayed on display device 129 of admindevice A 120, and that includes a button prompting the user of thatdevice to share digital information on the family cloud. Upon the user'sselection of that button via user input device 129′, e.g., a touchscreen on the admin device A, the GUI may display a field or windowprompting the user to enter a text-based message to be shared or toselect a photograph, video, or other digital medium to be shared, usinginput device 129′. The admin application on admin device A then maytransmit the selected digital information to the embedded device (step413), e.g., via the connection established in step 411.

The embedded device side of method 400 continues with receiving at theembedded device, within the family cloud application, the digitalinformation from admin device A (step 422). For example, sharing module115 of family cloud application 113 illustrated in FIG. 1 may receivethe digital information via the connection established in step 421.

At the embedded device, method 400 may continue with the family cloudapp transmitting the received digital information to a storage device(step 423). For example, as noted above, embedded device 110 illustratedin FIG. 1 may include an I/O port (not specifically illustrated) towhich an external storage device 171 may be connected, or alternativelyor additionally may include an internal storage device. Usefully, thecapacity of the internal or external storage device may be selected bythe user, may be relatively large for relatively low cost (e.g., 1 TB ormore for $100 or less), and may be upgraded or replaced substantiallywithout the need to modify embedded device 110. In one illustrativeembodiment, sharing module 115 of family cloud application 113 maytransmit the received digital information to external storage device 171via the I/O port for storage. Note that step 423 optionally may beomitted, in which case the digital information may be stored temporarilyin computer readable medium 112, or may be performed at a different timeduring execution of method 400.

Continuing on the embedded device side, method 400 includesautomatically sending a push notification of the digital information toany family devices that have enrolled to the cloud based on the storedIDs for the enrolled family devices (step 424). For example, push module116 illustrated in FIG. 1 may prepare a message relating to the digitalinformation, may retrieve the IDs 119 for all enrolled family devicesfrom computer-readable medium 112, and may send the message and the IDsto GPNS 180 via ISP 170 and the Internet, and optionally also via athird-party notification service. The GPNS 180 then may send the messagein the form of a push notification to the family devices for which itreceived IDs from embedded device 110. Methods of sending pushnotifications via a Global Push Notification Server or a third-partynotification service are known in the art. Alternatively, if any of thefamily devices are in the LAN environment of the embedded device, thenthe embedded device instead may notify such family devices of thedigital information using a direct message, rather than a pushnotification.

The message prepared by push module 116 may include the digitalinformation itself, or may include a text-based description of thedigital information, or may include a link to the digital informationstored within the internal storage device or external storage device 171connected to embedded device 110. For example, push notificationservices may only accept messages of a limited size, e.g., 256 bytes inthe case of the Apple Push Notification Service, at present. If thedigital information is sufficiently small as to be accepted by theGlobal Push Notification Server or third-party notification service,e.g., is a text-based message, or if any of the family devices are inthe LAN environment of the embedded device, then the digital informationmay be pushed directly to the family devices. However, if the digitalinformation is too large to be accepted by the Global Push NotificationServer or third-party notification service, e.g., is a photograph orvideo, and if the family devices are not in the LAN environment of theembedded devices, then the message may include a description of the filename or type of the digital information, and any description of thedigital information that the user of admin device A may have included,based upon which a family member may retrieve the digital informationfrom the embedded device. Alternatively, push module 116 may generatewithin the message a link based on HTML code that identifies the filename of the digital information, and a source from which thatinformation may be retrieved, e.g., the internal storage device orexternal storage device 171 connected to embedded device 110.

On the mobile device side of method 400 illustrated in FIG. 4, anexemplary family device B then receives the push notification of thedigital information, e.g., via a Global Push Notification Server orthird-party push notification service, or directly from the embeddeddevice if the family device B is in the LAN environment of the embeddeddevice (step 431). If the digital information itself is within the pushnotification, e.g., is of a sufficiently small size to be accepted bythe Global Push Notification Server or third-party push notificationservice, or if the family device B is in the LAN environment of theembedded device, then the digital information may be displayed (step431). For example, sharing module 136 of family device B 130-Billustrated in FIG. 1 may include a GUI that causes display device 139to display the received digital information.

However, if the push notification included a description of or a link tothe digital information rather than the digital information itself,e.g., if the digital information was too large to be accepted by theGlobal Push Notification Server or third-party push notificationservice, and family device B is not in the LAN environment of theembedded device, then method 400 continues on the mobile device sidewith exemplary family device B requesting the digital information fromthe embedded device responsive to the push notification (step 432). Forexample, if the push notification included a description of the digitalinformation, then the GUI of sharing module 136 of family device B 130-Billustrated in FIG. 1 may cause display device 139 to display a screenvia which the user may access and navigate the contents of an internalstorage device or external storage device 171 connected to embeddeddevice 110 so as to locate the information and then to request theinformation from the embedded device. Or, for example, if the pushnotification included a link to the digital information, then sharingmodule 136 automatically may select the link so as to request theinformation from the embedded device, or the user may select the link soas to request the information from the embedded device. Note that such arequest for the digital information need not be made immediately afterthe family device B receives the notification, but may be made at anysuitable or convenient time for the user or the family device. Indeed,the family device B need not necessarily ever request the digitalinformation from the embedded device. However, as described below withreference to FIG. 5, in some embodiments the embedded device may storerules that cause the embedded device to transfer the digital informationto the family device B at a later time if the family device connects tothe embedded device and that information had not yet been retrieved.

Method 400 continues on the embedded device side with the family cloudapplication retrieving the digital information from the storage deviceand transmitting the digital information to exemplary family device Bresponsive to the received request from that device (step 425). Forexample, sharing module 115 illustrated in FIG. 1 may receive therequest, and responsive to the request may access external storagedevice 171 via an I/O port or an internal storage device, may retrievethe digital information from the internal or external device, and maytransmit the digital information to family device B 130-B.

On the mobile device side, e.g., at family device B, the familyapplication then receives the digital information from the embeddeddevice and displays it to the family member (step 433). For example,sharing module 136 illustrated in FIG. 1 preferably includes a GUI thatcauses display device 139 to display the digital information to thefamily member.

Note that although method 400 is described with reference to the digitalinformation originating at admin device A and being received at familydevice B, it should be understood that the steps of the method suitablymay be modified to permit any mobile device enrolled in the family cloudto share digital information with the other mobile devices enrolled inthe family cloud in a manner analogous to that illustrated in FIG. 4.

Additionally, the embedded device may facilitate or control the sharingof information via the family cloud based on one or more rules therein,e.g., rules 1 . . . M 118 within family cloud application 113 stored incomputer-readable medium 112 of embedded device 110 illustrated inFIG. 1. For example, FIG. 5A illustrates steps executed by a embeddeddevice during an exemplary method 501 for soliciting digital informationfrom or transmitting information to an enrolled mobile device, e.g.,admin device A or any of family devices B . . . N 130-B . . . N, basedon rules within the embedded device relating to the time of the mobiledevice's last connection to the embedded device. Method 501 may beginwith connecting to the enrolled device at the embedded device (step511). Such a connection may be made in any suitable manner, such as viaa direct Wi-Fi connection between the mobile device and embedded device110; via a Wi-Fi connection between the mobile device and a differentembedded device and through the Internet based on the WAN IP address ofembedded device 110; or through a connection between the mobile deviceand a cellular data network such as 3G or 4G and through the Internetbased on the WAN IP address of embedded device 110.

Method 501 may continue with the embedded device, within the familycloud application, determining the time of its last connection to theenrolled mobile device (step 512). For example, one of the rules 1 . . .M 118 illustrated in FIG. 1 may cause sharing module 115 within familycloud application 113 to store within computer-readable medium 112 themost recent time at which the enrolled mobile device connected to theembedded device, or even a log of times at which the enrolled mobiledevice connected to the embedded device. Another of the rules 1 . . . M118 illustrated in FIG. 1 may cause sharing module 115 to determine thetime of the enrolled device's last connection based on such storedinformation, upon the connection of that device to the embedded devicein step 511.

Method 501 further includes the embedded device, within the family cloudapplication, applying one or more rules based on the time of lastconnection to the enrolled mobile device (step 513). In one example,within the family cloud application, the embedded device automaticallymay transmit a notification to the enrolled mobile device solicitingupload of digital information if a predetermined period has lapsed (step514). For example, one of the rules 1 . . . M 118 may cause sharingmodule 115 to determine the period between the present time and the timeof the enrolled device's last connection, to compare that period to apredetermined period stored within computer-readable medium 112, and totransmit the notification to the enrolled mobile device if the period isgreater than the predetermined period. The predetermined period may be aday, a week, or a month, or other suitable value that may bepreprogrammed or may be selected by the administrator via a suitable GUIgenerated by sharing module 126 of admin device A 120. The notificationmay tell the user that they have not connected to the embedded devicefor more than that predetermined period, and ask the user whether hewould like to share any digital information obtained during that period,e.g., may say something to the effect of, “You have not connected to thefamily cloud for more than one week. Do you have any photos or videos toshare?” Responsive to the notification, the user may select and transmitdigital information to the embedded device, and the embedded device mayshare that digital information with other enrolled devices, in a manneranalogous to that described above with reference to FIG. 4.

In another example, within the family cloud application, the embeddeddevice automatically may transmit to the enrolled mobile device anydigital information stored within the internal or external storagedevice since the time of last connection (step 515). For example,although the push module of the embedded device may send pushnotifications of digital information to any enrolled devices, asdescribed above with reference to FIG. 4, it may be the case that theenrolled mobile device connecting to the embedded device in step 511 hadnot yet retrieved that digital information from the embedded device. Oneof the rules 1 . . . M 118 may cause sharing module 115 to determinewhether any digital information has been stored within the internal orexternal storage device since the time of the enrolled device's lastconnection to the embedded device. If so, then the rule may causesharing module 115 to transmit that digital information to the enrolledmobile device via the connection established in step 511. Accordingly,the enrolled mobile device or the user thereof need not necessarilyproactively retrieve digital information from the embedded device. Thatis, steps 432 and 425 of method 400 illustrated in FIG. 4 need notnecessarily be executed for the embedded device to transmit to themobile device digital information, particularly digital information thatis too large to be sent via the Global Push Notification Server orthird-party push notification service.

Other types of rules for facilitating sharing digital informationbetween family devices enrolled to the family cloud may be envisioned.For example, FIG. 5B illustrates steps executed by a embedded deviceduring an exemplary method 502 for transmitting information to anenrolled mobile device, e.g., admin device A or any of family devices B. . . N 130-B . . . N, based on rules within the embedded devicerelating to the present location of the mobile device. Method 502illustrated in FIG. 5B may facilitate the sharing and enjoyment ofdigital information among enrolled mobile devices by sending informationthat may remind the users thereof of an earlier trip to the samelocation.

Method 502 may begin with connecting to the enrolled device at theembedded device (step 521). Such a connection may be made in anysuitable manner, such as via a direct Wi-Fi connection between themobile device and embedded device 110; via a Wi-Fi connection betweenthe mobile device and a different embedded device and through theInternet based on the WAN IP address of embedded device 110; or througha connection between the mobile device and a cellular data network suchas 3G or 4G and through the Internet based on the WAN IP address ofembedded device 110.

Method 502 may continue with the embedded device, within the familycloud application, determining the present location of the enrolledmobile device (step 522). For example, one of the rules 1 . . . M 118illustrated in FIG. 1 may cause sharing module 115 within family cloudapplication 113 to determine the present location of the enrolled mobiledevice based on the connection established in step 521. Informationabout the device's present location, such as the device's globalpositioning system (GPS) coordinates, automatically may be transferredto the embedded device during connection step 521, and indeed thesharing module 126 or 136 within the mobile device may be configured toprovide such location information automatically when connecting to theembedded device. Alternatively, one or the rules 1 . . . M 118 may causesharing module 115 to request such location information from theenrolled mobile device, and sharing module 126 or 136 may be configuredto respond to such a request by providing the mobile device's presentlocation.

Method 502 continues with the embedded device, within the family cloudapplication, applying one or more rules based on the present location ofthe enrolled mobile device (step 523). In one illustrative example,within the family cloud application, the embedded device automaticallymay transmit to the enrolled mobile device any digital informationstored within the internal or external storage device relating to thepresent location of the mobile device (step 524). One of the rules 1 . .. M 118 may cause sharing module 115 to determine whether any digitalinformation that is stored within the internal or external storagedevice relates to the present location of the mobile device. Forexample, the internal or external storage device may store, along withthe digital information itself, locations respectively associated withthe digital information. Such locations may be associated with thedigital information because a user had tagged the digital informationwith metadata describing the location at which the digital informationwas obtained using techniques known in the art; or because the deviceused to obtain the digital information automatically tagged the digitalinformation with such metadata, e.g., the device was a digital cameraprogrammed to tag digital images with metadata containing the GPScoordinates of the camera at the time the images are obtained; orbecause the sharing module 126 or 136 of the mobile device is configuredto tag the digital information with metadata describing the location ofthe mobile device at the time the mobile device transmits the digitalinformation to the embedded device for sharing in accordance with method400 of FIG. 4; or by any other suitable method.

If sharing module 115 determines that any digital information storedwithin the internal or external storage device relates to the presentlocation of the enrolled mobile device, e.g., includes metadatadescribing a location that is sufficiently close to the device's presentlocation, then the rule may cause sharing module 115 to transmit all ora subset that digital information to the enrolled mobile device via theconnection established in step 521. A definition of what may be a“sufficiently close” location, and whether to transmit all or only asubset of the digital information, may be preprogrammed or may beselected by the administrator via a suitable GUI generated by sharingmodule 126 of admin device A 120. Preferably, such a GUI also may permitthe admin device A 120 to exclude the mobile device's usual locationsfrom the rule, e.g., the user's home, work place, and daily travelroute, and to define how many items of digital information should besent, so that the user may not continually receive digital informationrelating to such locations, and may not receive a large volume ofdigital information, but preferably receives only one or a low number ofitems of digital information and only for less-frequently visitedlocations, such as vacation destinations.

The digital information may be transmitted during step 524 using a pushnotification such as described above with reference to FIG. 4,subsequent to which the mobile device may request the digitalinformation; or may be transmitted via a direct Wi-Fi connection betweenthe mobile device and embedded device 110; via a Wi-Fi connectionbetween the mobile device and a different embedded device and throughthe Internet; or through a connection between the mobile device and acellular data network such as 3G or 4G and through the Internet.Accordingly, the digital information may be transferred to the enrolledmobile device at a time that is not necessarily related to the time atwhich the digital information initially was transmitted to or stored bythe embedded device during method 400 illustrated in FIG. 4.

Indeed, digital information may be shared among enrolled mobile devicesbased on any suitable rule relating to the present time. For example,FIG. 5C illustrates steps executed by a embedded device during anexemplary method 503 for transmitting information to an enrolled mobiledevice, e.g., admin device A or any of family devices B . . . N 130-B .. . N, based on rules within the embedded device relating to the presenttime. Method 503 illustrated in FIG. 5C may facilitate the sharing andenjoyment of digital information among enrolled mobile devices bysending information that may remind the users thereof of an earlier timeor event that relates to the present time.

Method 503 may begin with the embedded device, within the family cloudapplication, determining the time (step 531). For example, one of therules 1 . . . M 118 illustrated in FIG. 1 may cause sharing module 115within family cloud application 113 to determine the present time, e.g.,by accessing a system clock within embedded device 110.

Method 503 continues with the embedded device, within the family cloudapplication, applying one or more rules based on the present time (step532). In one illustrative example, within the family cloud application,the embedded device automatically may transmit to the enrolled mobiledevice any digital information stored within the internal or externalstorage device obtained at a fixed time previous to the present time(step 533). One of the rules 1 . . . M 118 may cause sharing module 115to determine whether any digital information that is stored within theinternal or external storage device was obtained at a predetermined timeprevious to the present time, e.g., one week, one month, one year, twoyears, five years, ten years, or any other suitable amount of timeprevious to the present time. If sharing module 115 determines that anydigital information stored within the storage device was obtained at thepredetermined time previous to the present time, e.g., was obtained oneweek, one month, one year, two years, five years, or ten years previousto the present time, then the rule may cause sharing module 115 totransmit all or a subset of that digital information to the enrolledmobile device via the connection established in step 531. A definitionof the predetermined time may be preprogrammed or may be selected by theadministrator via a suitable GUI generated by sharing module 126 ofadmin device A 120. Preferably, such a GUI may permit the admin device A120 to define how many items of digital information should be sent, sothat the user may not receive a large volume of digital information, butpreferably receives only one or a low number of items of digitalinformation that may remind the user of an earlier time.

The digital information may be transmitted during step 524 using a pushnotification such as described above with reference to FIG. 4,subsequent to which the mobile device may request the digitalinformation; or may be transmitted via a direct Wi-Fi connection betweenthe mobile device and embedded device 110; via a Wi-Fi connectionbetween the mobile device and a different embedded device and throughthe Internet; or through a connection between the mobile device and acellular data network such as 3G or 4G and through the Internet.Accordingly, the digital information may be transferred to the enrolledmobile device at a time that is not necessarily related to the time atwhich the digital information initially was transmitted to or stored bythe embedded device during method 400 illustrated in FIG. 4.

In another illustrative example, within the family cloud application,the embedded device automatically may transmit to the enrolled mobiledevice any digital information stored within the internal or externalstorage device relating to an upcoming event (step 534). One of therules 1 . . . M 118 may cause sharing module 115 to determine whetherany digital information that is stored within the internal storagedevice or external storage device 171 relates to an upcoming event, suchas a holiday, anniversary, or birthday. For example, the storage devicemay store, along with the digital information itself, descriptions ofevents respectively associated with the digital information. Suchdescriptions of events may be associated with the digital informationbecause a user had tagged the digital information with metadatadescribing the event associated with the digital information usingtechniques known in the art; or because the sharing module 126 or 136 ofthe mobile device is configured to prompt the user to tag the digitalinformation with metadata describing the location of the mobile deviceat the time the mobile device initially obtains the digital informationor at the time that it transmits the digital information to the embeddeddevice for sharing in accordance with method 400 of FIG. 4; or by anyother suitable method. Such metadata may contain the term “holiday,”“anniversary” or “birthday” or another term relating to an event, andmay include the name of a friend or family member, e.g., “Suzie'sbirthday.” One or more of the rules 1 . . . M 118 may cause sharingmodule 115 to compare such terms to words that may appear in entrieswithin the user's calendar, which may be among the digital informationstored on an internal storage device or external storage device 171, andto determine whether the term matches the word and the date of the entrywithin the user's calendar is on the present date or is approaching(e.g., is one week or one day from the present date). That is, sharingmodule 115 may determine by such a method, or by any other suitablemethod, that an event is on an upcoming date or on the present date, andthat digital information stored within the storage device relates to aprior occurrence of that event.

If sharing module 115 determines that any digital information storedwithin the internal or external storage device relates to the upcomingevent, then the rule may cause sharing module 115 to transmit all or asubset of that digital information to the enrolled mobile device via theconnection established in step 531. A definition of events for which toperform such transmission may be preprogrammed or may be selected by theadministrator via a suitable GUI generated by sharing module 126 ofadmin device A 120. Preferably, such a GUI may permit the admin device A120 to define how many items of digital information should be sent, sothat the user may not receive a large volume of digital information, butpreferably receives only one or a low number of items of digitalinformation that may remind the user of an earlier event.

The digital information may be transmitted during step 534 using a pushnotification such as described above with reference to FIG. 4,subsequent to which the mobile device may request the digitalinformation; or may be transmitted via a direct Wi-Fi connection betweenthe mobile device and embedded device 110; via a Wi-Fi connectionbetween the mobile device and a different embedded device and throughthe Internet; or through a connection between the mobile device and acellular data network such as 3G or 4G and through the Internet.Accordingly, the digital information may be transferred to the enrolledmobile device at a time that is not necessarily related to the time atwhich the digital information initially was transmitted to or stored bythe embedded device during method 400 illustrated in FIG. 4.

The family cloud further may permit mobile devices to share informationwith one another on a high priority basis. For example, if there is afamily emergency such as an accident, a security breach, or a fire, thepresent embedded device may facilitate the rapid sharing of messagesamong the mobile devices relating to such an emergency. FIG. 5Dillustrates steps executed by an embedded device and by mobile devicesduring an exemplary method 504 for sharing digital information on a highpriority basis using a family cloud.

On the mobile device side, method 504 begins with the admin or familyapplication at a first enrolled mobile device receiving a “FamilyEmergency” message from the user (step 541). For example, sharing module126 of admin device A and sharing module 136 of family devices B . . . N130-B . . . 130-N each preferably includes a GUI that may be displayedon display device 129 of admin device A 120, and that includes a buttonprompting the user of that device to indicate a “Family Emergency.” Uponthe user's selection of that button via a user input device on themobile device, the GUI may display a field prompting the user to entertext describing the family emergency, e.g., “I hear someone trying tobreak in.” Preferably, based on the use of the “Family Emergency”button, sharing module 126 or 136 automatically includes within themessage the name and location of the mobile device's user, and anindication that there is an emergency. The admin application or familyapplication then may transmit the message to the embedded device (step542). For example, sharing module 126 or 136 may initiate a connectionto the embedded device in a manner such as described above, and maytransmit the indication to the embedded device via such a connection.

On the embedded device side, method 504 continues with the embeddeddevice receiving the “Family Emergency” message within the family cloudapplication (step 551). For example, sharing module 115 may receive themessage, and based on one or more of rules 1 . . . M 118 may determinefrom the content of the message, e.g., from the indication within themessage, that there is an emergency and that therefore the otherenrolled devices should be notified of the emergency on a high prioritybasis. The embedded device then automatically may send a “FamilyEmergency” push notification to the other enrolled family devices on ahigh priority basis (step 552). For example, push module 116 may prepareand send a “Family Emergency” push notification to Global PushNotification Server 180, optionally via a third party push notificationservice, and internally may prioritize the preparation and sending ofthat notification above other push notifications that may relate toother types of digital information to be shared on the family cloud. Thepush notification preferably includes the text entered by the user, theuser's name and location, and an indication that there is a “FamilyEmergency.” Note that if any of the other enrolled family devices are inthe LAN environment of the embedded device, then the embedded deviceinstead may send the “Family Emergency” notification using a directmessage, rather than a push notification.

Returning to the mobile device side, method 500 continues with the otherenrolled family devices receiving, within the admin or familyapplication, the “Family Emergency” push notification (step 561). Forexample, sharing module 126 of admin device 120 and sharing module 136of family devices B . . . N 130-B . . . N illustrated in FIG. 1 mayinclude a GUI that causes display device 139 to display the content ofthe push notification in such a manner as to quickly alert the user thattheir attention to the emergency may be required. Preferably, the otherenrolled family devices, within the admin or family application,transmit an acknowledgment of receipt to the embedded device (step 562).Accordingly, if any of the other enrolled family devices do not receivethe “Family Emergency” push notification at step 561, then they may nottransmit an acknowledgment of receipt to the embedded device.

Then, if the family cloud application of the embedded device does notreceive an acknowledgment from any of the enrolled family devices, thenthe application preferably re-sends the “Family Emergency” pushnotification to that enrolled family device (step 553), following whichsteps 561, 562, and 553 may repeat as needed until that enrolled familydevice transmits an acknowledgment to the embedded device. Note that thefamily cloud application of the embedded device optionally may beconfigured to re-send the “Family Emergency” push notification to anunresponsive enrolled family device a limited number of times, e.g.,five times, or ten times, or more. It also should be understood thatmethod 504 illustrated in FIG. 5D suitably may be modified so as rapidlyto distribute any type of message among enrolled family devices, andthat the messages need not necessarily pertain to emergencies. However,method 504 may provide a particularly useful way of rapidly bringingemergencies to the attention of family members, friends, and the like.

It should be appreciated that the various above-described rule-basedactions that may be taken by the embedded device are intended to bepurely illustrative, and not limiting. Other rules may be envisioned,and such rules optionally may be omitted.

Methods of Maintaining Communication with Mobile Devices

As noted above, mobile devices enrolled to the family cloud maycommunicate with the embedded device via a direct Wi-Fi connectionbetween the mobile device and the embedded device in a LAN environment;via a Wi-Fi connection between the mobile device and a differentembedded device and through the Internet based on the WAN IP address ofthe embedded device; or through a connection between the mobile deviceand a cellular data network such as 3G or 4G and through the Internetbased on the WAN IP address of the embedded device. For connecting viaWi-Fi in a LAN environment, the embedded device's ESSID and the accesscredential for use in connecting to the embedded device may be providedto the mobile device during enrollment to the family cloud. Analogously,for connecting via the Internet, e.g., via a different embedded deviceor via a cellular data network, the embedded device's WAN IP address foruse in connecting to the embedded device may be provided to the mobiledevice during enrollment to the family cloud.

However, as is known in the art, internet service providers (ISPs) suchas ISP 170 illustrated in FIG. 1 may dynamically assign WAN IP addressesto network devices such as gateways, so as to save limited numbers ofstatic WAN IP addresses. Accordingly the WAN IP address of embeddeddevice 110 may change from time to time. Unless informed of such achange, the family devices enrolled to that embedded device's familycloud may be unable to connect to the embedded device via the Internetbecause they would not know the embedded device's new WAN IP address.Although services based on the known dynamic domain name system (DDNS)potentially may be used to inform mobile devices of the embeddeddevice's new WAN IP address, e.g., in which the mobile devices use adomain name to retrieve a new WAN IP address from a DDNS server, asimpler method based on the embedded device's push notificationfunctionality instead may be used to maintain communication between theembedded device and mobile devices.

Specifically, FIG. 6 illustrates steps executed by an embedded deviceand by mobile devices during an exemplary method 600 for maintaining afamily cloud after the embedded device receives a new WAN IP address. Onthe embedded device side, method 600 begins with the embedded devicereceiving a new WAN IP address from an ISP (step 611). For example, ISP170 to which embedded device 110 is connected periodically may assign anew WAN IP address to the embedded device, of which the embedded devicemay become aware using known techniques.

The embedded device then, within the family cloud application,automatically may send a push notification with the new WAN IP addressto enrolled mobile devices (step 612). For example, the pushnotification may include a link based on HTML code for use in causingthe enrolled device to configure itself appropriately so as to connectto the embedded device based on the new WAN IP address.

On the mobile device side of method 400, the enrolled mobile device thenmay receive the push notification of the new WAN IP address for theembedded device (step 621), and may connect to the embedded device basedon the new WAN IP address responsive to the push notification (step622). Such a connection may be established analogously as during theenrollment process described further above with reference to FIG. 3. Themobile devices then may continue to communicate with the embeddeddevice, and may share digital information using the family cloud of thatembedded device, based on the new WAN IP address.

Note that other methods for maintaining communication between embeddeddevices and mobile devices alternatively suitably may be used, such asbased on DDNS. As is known in the art, DDNS is a service that mapsInternet domain names to WAN IP addresses. The DDNS service may monitorthe WAN IP address of a network device, and if the WAN IP address of thedevice changes, the DDNS service may update the mapping of the Internetdomain name to the new WAN IP address. Accordingly, maintainingcommunication with the first and second mobile devices may include thefirst and second mobile devices retrieving the new embedded device WANIP address from a dynamic domain name system (DDNS) server.

Multiple Embedded Device-Based Systems and Methods

As mentioned above and as described in greater detail below withreference to FIGS. 7-10, two or more embedded devices such as thatillustrated in FIG. 1 may be networked together via the Internet so asto provide a merged family cloud that may facilitate mobile devicessharing digital information with one another to an even greater extent.Such embedded devices preferably are LAN-based, e.g., are configured toprovide LAN environments such as Wi-Fi connections to mobile deviceswithin range, and preferably also have WAN IP addresses so that devicesoutside of the LAN environment may access the embedded devices uponpresentation of a suitable access credential.

Specifically, FIG. 7 illustrates an exemplary system 700 that includes afirst embedded device C 710 and a second embedded device D 711, althoughshould be appreciated that system 700 may include any suitable number ofembedded devices connected to one another in a manner analogous to thatof embedded device C 710 and embedded device D 711. Embedded device C710 is connected to admin device C 720, to one or more family devices C1730, to external storage 740 (internal storage not illustrated), to ISP750, and to Global Push Notification Server (GPNS) 760, optionally via athird-party notification service (not illustrated), each of whichcomponents may be configured analogously as described above withreference to FIG. 1. Similarly, embedded device D 711 is connected toadmin device D 721, to one or more family devices D1 731, to externalstorage 741 (internal storage not illustrated), to ISP 751, and to GPNS760, optionally via a third-party notification service (notillustrated), each of which components may be configured analogously asdescribed above with reference to FIG. 1. Additionally, embedded deviceC and D 710, 711 each respectively may include a merge module 770, 771,and admin devices C and D 720, 721 each respectively may include a mergerequest module 780, 781. Merge modules 770, 771 and merge requestmodules 780, 781 preferably are configured to facilitate networking ofembedded devices C and D with one another and the merging of theembedded devices' respective family clouds, as now will be describedwith reference to FIGS. 8A-8E. It should be appreciated that anysuitable number of embedded devices and mobile devices may be networkedtogether using the principles provided herein.

FIG. 8A illustrates steps in an exemplary method 800 executed at firstand second mobile devices and at first and second LAN-based embeddeddevices to establish secure connections via which they may share digitalinformation with one another. Method 800 includes enrolling admin deviceC to the family cloud of embedded device D (step 801), e.g., in themanner described above with reference to FIG. 3. Preferably, admindevice C is enrolled as the administrator for embedded device C, and isenrolled as a family member for embedded device D, and thus maycommunicate securely (e.g., via SSH) with embedded devices C and D; andadmin device D is enrolled as the administrator for embedded device D,and thus may communicate securely (e.g., via SSH) with embedded deviceD. Accordingly, embedded device D stores the identifiers for both ofadmin devices C and D, and admin device C stores the WAN IP addressesand respective access credentials for both of embedded devices C and D.Preferably, the users of admin devices C and D agree with one another tomerge the family clouds of the embedded devices for which they areadministrators. For example, the user of admin device C may request tojoin the family cloud of embedded device D, e.g., via email, telephone,text messaging, or the like and the user of admin device D agrees, orthe user of admin device D likewise may invite the user of admin deviceC to join the family cloud of embedded device D and the user of admindevice C agrees.

Method 800 illustrated in FIG. 8A continues with admin device D, withinthe admin app, generating a request to merge the family clouds ofembedded devices C and D (step 802), e.g., upon user selection of asuitable button within a GUI generated by merge request module 781illustrated in FIG. 7. Merge request module 781 of admin device D thentransmits the request to embedded device D.

Referring again to FIG. 8A, responsive to the request received fromadmin device D, embedded device D sends a push notification includingthe WAN IP address of embedded device D to admin device C, as well as anaccess credential for embedded device C to use to securely connect toembedded device D (step 803). Admin device C, responsive to the pushnotification, then sends the WAN IP address and credential of embeddeddevice D to embedded device C via an SSH connection (step 804).

Embedded device C then may establish an SSH connection with embeddeddevice D based on the received WAN IP address and access credential, andthen may send the WAN IP address and access credential of embeddeddevice C to embedded device D via SSH (step 805). For example, mergemodule 770 of embedded device C 710 may transmit the WAN IP address andaccess credential of embedded device C to merge module 771 of embeddeddevice D via such an SSH connection.

Embedded device D then may establish an SSH connection with embeddeddevice C based on the received WAN IP address and credential of embeddeddevice C (step 806), thus resulting in a secure bidirectionalcommunication pathway between embedded devices C and D via which mobiledevices respectively enrolled to the clouds of the embedded devices mayshare digital information with one another. Preferably, embedded devicesC and D, within the admin application, respectively send anacknowledgment of the successful merge to one another (step 807).

Note that in other embodiments, a mobile device need not necessarily bepreviously enrolled to a given embedded device in order to merge thefamily cloud of that embedded device with the family cloud of anotherembedded device. For example, FIG. 8B illustrates steps executed byfirst and second mobile devices during an alternative exemplary method810 for initiating the merge of the family clouds of first and secondembedded devices. Specifically, method 810 begins on the side of a firstmobile device, e.g., admin device C 720 illustrated in FIG. 7, byenrolling that device to the family cloud of a first embedded device,e.g., embedded device C 710 (step 811). At the same time, or more likelyat an earlier or later time, method 810 continues on the side of asecond mobile device, e.g., admin device D 721 illustrated in FIG. 7, byenrolling that device to the family cloud of a second embedded device,e.g., embedded device D 711 (step 821). Exemplary methods of enrollingadmin devices to family clouds are described above with reference toFIG. 2. Note that steps 811 and 821 may occur well before the remainingsteps of method 810; that is, the family clouds of embedded devices Cand D may be established for any suitable amount of time before thefamily clouds of those two embedded devices are merged.

Method 810 further includes, at the second mobile device side, receivingwithin the admin application of admin device D the email address for theadmin of embedded device C's family cloud (that is, the user of admindevice C) and a request to merge the family clouds of embedded devices Cand D (step 822). For example, merge request module 781 of admin deviceD 721 illustrated in FIG. 7 preferably includes a GUI that may bedisplayed on the display device (not specifically illustrated) of admindevice D 721, and that includes a button prompting the administrator ofthat device to invite the administrator of another family cloud to mergefamily clouds. Upon the administrator's selection of that button via auser input device (not specifically illustrated), e.g., a touch screenon the admin device D, the GUI may display a field prompting the user totype in the email address of the administrator to be invited using theinput device, or an interface permitting the administrator to select anemail address from a contact list or address book stored on admin deviceD, using the user input device.

Method 810 illustrated in FIG. 8B may continue on the mobile device sideby automatically generating, within the admin application on admindevice D, a message that contains an invitation and a link to merge thefamily clouds of embedded devices C and D (step 823). Preferably, theadmin application generates such a message using a native emailapplication within admin device D, and the email is sent to admin deviceC responsive to administrator approval (step 823). For example, mergerequest module 781 illustrated in FIG. 7 may generate the message withlink within a native email application (not specifically illustrated) onadmin device D 721, and the administrator may approve and send themessage by clicking “send” within the native email application. Themerge request module 781 may generate the link based on HTML code thatincludes the ID for admin device D for embedded device C's use inmerging the family clouds of embedded devices C and D. The admin deviceD then may send the email to admin device C via an appropriatecommunications channel, e.g., via a Wi-Fi connection to embedded deviceD 711 and via ISP 751 to the Internet; via a Wi-Fi connection to adifferent embedded device and through the Internet; or through acellular data connection such as 3G or 4G and through the Internet. Notethat for step 823, a Wi-Fi connection to embedded device D may be usedif admin device D is in the LAN environment of embedded device.

Method 810 continues on the side of a first mobile device, specificallyadmin device C, at which a native email application therein receives theemail message with the invitation to merge the family clouds of embeddeddevices C and the link to download the family application from an onlineapp store (step 812). For example, a native email application on admindevice C 720 may display the email to the family member and may promptthe administrator to select the link using an input device.

FIG. 8C illustrates steps executed by first and second mobile devicesand by first and second embedded devices during an exemplary method 811for completing the merge of the family clouds of the first and secondembedded devices following the initiation of such a merge in method 810illustrated in FIG. 8B.

Specifically, method 811 illustrated in FIG. 8C continues from step 812illustrated in FIG. 8B at the first mobile device, specifically withinadmin device C, in which the admin application transmits to embeddeddevice C a request to merge with the cloud of embedded device Dresponsive to the administrator's selection of the link (step 813). Forexample, the HTML code within the link may cause merge request module780 of admin device C 720 to transmit to embedded device C 710 the IDfor admin device D, which the embedded device C may interpret as aninstruction to merge with the cloud of embedded device D, and tocommunicate with admin device D to do so.

On the side of the first embedded device, specifically embedded deviceC, method 810 continues with the embedded device C, from within thefamily cloud application, sending a push notification including anaccess credential for embedded device D to access embedded device C andthe WAN IP address of embedded device C to admin device D responsive tothe received request to merge (step 831). For example, embedded device C710 may send its own WAN IP address and access credential (such as alogin and password or encryption key) to admin device D 721, in the formof a push notification. In one illustrative embodiment, the pushnotification may include an HTML link that includes the WAN IP addressand access credential of embedded device C.

At the second mobile device side, method 810 continues with the admindevice D, within the admin application, receiving the push notificationwith the WAN IP address and credential for embedded device C, andresponding by transmitting the access credential and the WAN IP addressfor embedded device C to embedded device D (step 824). For example,merge request module 781 of admin device D may receive the pushnotification, which as noted above may include an HTML link thatincludes the access credential and the WAN IP address of embedded deviceC. Merge request module 781 may automatically select, or may prompt theadministrator for admin device D 721 to select, the link. Responsive toselection of the link, or otherwise responsive to the push notification,merge request module 781 of admin device D may transmit the accesscredential and WAN IP address for embedded device C 710 to embeddeddevice D 711.

At the side of the second embedded device, namely embedded device D, theaccess credential and WAN IP address for embedded device C may bereceived from admin device D within the family cloud application (step841). For example, merge module 771 of embedded device D 711 illustratedin FIG. 7 may receive the access credential and WAN IP address forembedded device C from merge request module 781 of admin device D, andthen may store that access credential and WAN IP address within thecomputer readable medium (not specifically illustrated) of embeddeddevice D. Then, at embedded device D, the family cloud applicationautomatically may submit a merge request to embedded device C based onthe access credential and WAN IP address for embedded device C (step842). For example, merge module 771 of embedded device D 711 maygenerate a message that includes the access credential and WAN IPaddress for embedded device D, and may transmit that message to embeddeddevice C.

At the side of the first embedded device, namely embedded device C, theaccess credential and the WAN IP address for embedded device D may bereceived and used to automatically merge the cloud of embedded device Cwith the cloud of embedded device D (step 832). Specifically, mergemodule 770 of embedded device C 710 may store the WAN IP address forembedded device D within the computer readable medium of embedded deviceC, and may establish an SSH connection with embedded device D based onthe WAN IP address and access credential. Preferably, embedded device C710, within the family cloud application, automatically sends a pushnotification of the successful merge of the family clouds of embeddeddevices C and D to admin devices C and D (step 833). Note, however, thatbecause bi-directional secure communication (e.g., SSH) has beenestablished between embedded devices C and D, push notification may notbe needed to inform admin devices C and D that the merge of the familyclouds has been successful; instead, simple messaging via theestablished connection may be used.

Following such storage and connection, merge module 770 of embeddeddevice C 710 may use the WAN IP address for embedded device D tocommunicate digital information to embedded device D. Conversely, mergemodule 771 of embedded device D 711 may store the access credential andWAN IP address for embedded device C (step 841), and may use the accesscredential and WAN IP address to establish an SSH connection withembedded device D to communicate digital information to embedded deviceD. Moreover, embedded device C also may receive and store the ID foradmin device D and so may communicate push notifications of digitalinformation to admin device D; and embedded device D also may receiveand store the ID for admin device C and so may communicate pushnotifications of digital information to admin device C. However, otherfamily devices that may be enrolled to the family cloud of embeddeddevice C may not necessarily be enrolled to the family cloud of embeddeddevice D, and family devices that may be enrolled to the family cloud ofembedded device D may not necessarily be enrolled to the family cloud ofembedded device C. Methods for synchronizing information betweenembedded devices C and D so as to share information among family members(or other users) who may be enrolled only to one of embedded devices Cand D are described further below with reference to FIGS. 9A and 9B.

Note that other methods of initiating merging of the clouds of embeddeddevice C 710 and embedded device D 711 illustrated in FIG. 7alternatively may be used. For example, initiation method 810 applies toa situation in which the administrator of the cloud for embedded deviceD requests to merge with the cloud of embedded device C. Alternativemethod 810′ described below with reference to FIG. 8D may be used inplace of method 810 illustrated in FIG. 8B for situations in which theadministrator of the cloud for embedded device C instead invites theadministrator of the cloud for embedded device D to merge with the cloudfor embedded device C.

Alternative method 810′ begins analogously as method 810, e.g., byenrolling admin device C to the family cloud of embedded device C (step811) and by enrolling admin device D to the family cloud of embeddeddevice D (step 821). Method 810′ then continues at step 814, at admindevice C, within the admin application, by receiving the email addressof the administrator of embedded device D's family cloud and a requestto merge the family cloud of embedded devices C and D (step 814). Suchan email and request may be received in a manner analogous to thatdescribed above with reference to step 822 of method 810.

Method 810′ then may continue by automatically generating a messagecontaining an invitation and a link to merge the family clouds ofembedded devices C and D, and responsive to the administrator's approvalsending the email message to the administrator for admin device D (step815). Such a message, link, approval, and sending may be performed in amanner analogous to that described above with reference to step 823. Themessage then may be received at admin device D (step 825) in a manneranalogous to that described above with reference to step 812. Then,responsive to the administrator's selection of the link, a reply messageautomatically may be generated that contains the ID for admin device Dand a link to approve the merge, and responsive to administratorapproval the email message may be sent to admin device C using thenative email application on admin device D (step 826). The reply messagemay be generated in a manner analogous to that described above withreference to step 323 of FIG. 3. Then, the email message may be receivedat admin device C (step 816) in a manner analogous to that describedabove with reference to step 812 of FIG. 8B. The process of merging theclouds of embedded devices C and D then may continue with method 811described above with reference to FIG. 8C.

FIG. 8E illustrates another exemplary method 850 that may be used tomerge the family clouds of embedded devices C and D. Method 850 includesrespectively enrolling admin devices C and D as the admin devices forembedded devices C and D, e.g., in the manner described above withreference to FIG. 3. Preferably, admin device C is enrolled as theadministrator for embedded device C, and thus may communicate securely(e.g., via SSH) with embedded device C; and admin device D is enrolledas the administrator for embedded device D, and thus may communicatesecurely (e.g., via SSH) with embedded devices C and D.

Method 850 illustrated in FIG. 8E continues with admin device D, withinthe admin app, generating a request to merge the family clouds ofembedded devices C and D (step 852), e.g., upon user selection of asuitable button within a GUI generated by merge request module 781illustrated in FIG. 7. Merge request module 781 of admin device D thentransmits the request to admin device C. In one illustrative embodiment,the request is in the form of an email that is prepared using a nativeemail application such as described in greater detail above and is sentto the user of admin device C.

Referring again to FIG. 8E, responsive to the request received fromadmin device D, the admin application of admin device C provides theidentifier of admin device C and preferably also the WAN IP address ofembedded device C to admin device D (step 853). For example, if therequest was in the form of an email, then admin device C may prepare andsend to the user of admin device D a reply email that contains theidentifier, such as described in greater detail above. Then, at admindevice D, the admin application transmits the received identifier ofadmin device C and WAN IP address of embedded device C to embeddeddevice D (step 854).

Embedded device D, within the family application, then sends a pushnotification of the WAN IP address of embedded device D to admin deviceC, along with an access credential that embedded device C may use tosecurely communicate with embedded device D (step 855). The admin app ofadmin device C then may transmit the received WAN IP address andcredential of embedded device D to embedded device C (step 856),preferably via an SSH connection.

Embedded device C then may establish an SSH connection with embeddeddevice D based on the received WAN IP address and access credential, andthen may send the WAN IP address and access credential of embeddeddevice C to embedded device D via SSH (step 857). For example, mergemodule 770 of embedded device C 710 may transmit the WAN IP address andaccess credential of embedded device C to merge module 771 of embeddeddevice D via such an SSH connection. Optionally, the SSH connectionestablished in step 857 may be “uni-directional,” for example ifembedded device C does not wish to permit embedded device D toproactively access digital information on embedded device C.

Embedded device D then may establish an SSH connection with embeddeddevice C based on the received WAN IP address and credential of embeddeddevice C (step 858), thus resulting in a secure bidirectionalcommunication pathway between embedded devices C and D via which mobiledevices respectively enrolled to the clouds of the embedded devices mayshare digital information with one another. Preferably, embedded devicesC and D, within the admin application, respectively send anacknowledgment of the successful merge to their respective admin devicesC and D (step 859).

It should be appreciated that any of the methods described above withreference to FIG. 1 suitably may be modified for use with system 700illustrated in FIG. 7. Additionally, it may be appreciated thatregardless of the particular manner in which the clouds of differentembedded devices are merged together, the digital information on one ofthe embedded devices conveniently may be synchronized with the digitalinformation on the other embedded devices via the merged cloud, so as tofacilitate the sharing of such information with users who may beenrolled to the respective clouds.

For example, FIG. 9A illustrates steps executed by embedded devices andby mobile devices during an exemplary method 900 for sharing digitalinformation between the mobile devices using a merged family cloud.Method 900 may begin on the mobile device side at step 911, in whichfamily device C1 (enrolled only to the family cloud of embedded deviceC), receives within the family application input selecting digitalinformation to share. Exemplary methods of receiving such input aredescribed further above with reference to step 412 of FIG. 4. Method 900may continue on the mobile device side at step 912, in which familydevice C1, within the family app, transmits the selected digitalinformation to embedded device C, e.g., in a manner analogous to thatdescribed above with reference to step 413 of FIG. 4.

Then, on the side of a first embedded device, specifically embeddeddevice C, the selected digital information is received within the familycloud application from family device C1 (step 921) and then may betransmitted to an internal or external storage device C (step 922),e.g., in a manner analogous to that described above with reference tostep 422 and 423 of FIG. 4. Within the family cloud application,embedded device C further may send a push notification of the digitalinformation to other mobile devices that may be enrolled to embeddeddevice C, e.g., admin device C, based on a rule (step 924).Additionally, within the family cloud application, embedded device Cautomatically may transmit the received digital information to embeddeddevice D, based on a rule (step 923). For example, embedded device C maysend a message containing the digital information to the stored WAN IPaddress for embedded device D. Preferably, but not necessarily, embeddeddevice C sends such digital information to embedded device D at apredefined synchronization period, e.g., once an hour, or once a day, oronce a week, so as to avoid the need to continuously communicate withembedded device D. Note that steps 923 and 924 may be performed in anysuitable order, or even concurrently. Then, on the side of a secondembedded device, specifically embedded device D, the family cloudapplication may receive the digital information from embedded device C(step 931), e.g., via the Internet, may transmit the received digitalinformation to internal or external storage device D (step 932), and maysend a push notification of the digital information to mobile devicesthat are enrolled to embedded device D (step 933), for example in themanner described above with reference to steps 422-424 illustrated inFIG. 4.

Depending on the particular type or source of the digital information,the sharing of that information between the embedded devices and themobile devices enrolled thereto may be prioritized. For example, FIG. 9Billustrates steps executed by embedded devices and by mobile devicesduring an exemplary method 901 for sharing high priority digitalinformation between the mobile devices using a merged family cloud.Specifically, certain messages generated by an administrator, such as anotification of a security break or a family emergency, may be assigneda higher priority and promptly synchronized between the embedded deviceson the merged cloud.

Method 901 may begin on the mobile device side at step 941, in whichadmin device C receives within the admin application input selecting anadmin notification. For example, the sharing module within the adminapplication on the admin device may include a GUI that causes an “adminnotification” button to be displayed, which the administrator may selectand use to enter a text message or other information to be assigned ahigh priority for sharing with other mobile devices in the merged cloud.Exemplary methods of receiving such input are described further abovewith reference to step 412 of FIG. 4. Method 901 may continue on themobile device side at step 942, in which the admin device C, within theadmin app, transmits the admin notification to embedded device C, e.g.,in a manner analogous to that described above with reference to step 413of FIG. 4.

Then, on the side of a first embedded device, specifically embeddeddevice C, the admin notification is received within the family cloudapplication from admin device C (step 951), e.g., in a manner analogousto that described above with reference to step 422 of FIG. 4. Within thefamily cloud application, embedded device C further may send a pushnotification of the digital information immediately to other mobiledevices that may be enrolled to embedded device C, e.g., admin device C,based on a rule (step 953). Additionally, within the family cloudapplication, embedded device C automatically may transmit the receiveddigital information immediately to embedded device D, based on a rule(step 952). For example, embedded device C may send a message containingthe admin notification to the stored WAN IP address for embedded deviceD. Preferably, embedded device C sends the message on a priority basis,e.g., internally prioritizes the message above other push notificationsor outgoing messages. Note that steps 952 and 953 may be performed inany suitable order, or even concurrently. Then, on the side of a secondembedded device, specifically embedded device D, the family cloudapplication may receive the admin notification from embedded device C(step 961), e.g., via the Internet, and may send a push notification ofthe digital information immediately to mobile devices that are enrolledto embedded device D (step 933), for example in the manner describedabove with reference to steps 422-424 illustrated in FIG. 4. Preferably,the family cloud applications of embedded devices C and D are configuredso as to recognize the priority nature of the admin notification basedon the content or format of the notification, and to handle thenotification on a priority basis accordingly.

As described above with reference to FIG. 6, the ISP to which anembedded device may be connected may dynamically assign a WAN IP addressto the embedded device, and accordingly the embedded device's WAN IPaddress may change from time to time. Occasionally, the WAN IP addressesof more than one embedded device within system 700 illustrated in FIG. 7may change at the same time; the present systems and methods readily maybe adapted to communicate the WAN IP address from one embedded device toanother, even if the WAN IP address of neither embedded device is knownto the other.

Specifically, FIG. 10 illustrates steps executed by embedded devices andby mobile devices during an exemplary method 1000 for maintainingcommunication between embedded devices, e.g., for maintaining a mergedfamily cloud after one or more of the embedded devices receives a newWAN IP address. Method 1000 includes, on the side of a first embeddeddevice, specifically embedded device C, receiving a new WAN IP addressfrom an ISP, e.g., as described above with reference to step 611illustrated in FIG. 6 (step 1011). Then, at embedded device C, withinthe family cloud application, a push notification of the new WAN IPaddress may be sent to enrolled mobile devices, e.g., in a manneranalogous to that described above with reference to step 612 illustratedin FIG. 6. Additionally, at embedded device C, within the family cloudapplication, a message with the new WAN IP address automatically may besent to embedded device D via the Internet based on the stored WAN IPaddress for embedded device D (step 1013).

On the side of the second embedded device, e.g., embedded device D, themessage may be received, and responsive to the message embedded device Dmay connect to embedded device C based on the new WAN IP address and maysend a success message to embedded device C (step 1021). However, if theWAN IP address for embedded device D that was stored in embedded deviceC was out of date, e.g., if the WAN IP address for embedded device Dchanged at approximately the same time as did the WAN IP address forembedded device C, then embedded device D may not receive the message atstep 1021.

On the side of the first embedded device, specifically embedded deviceC, if the family cloud application does not receive the success message,then the family cloud application may send a push notification of thenew WAN IP address to admin device D with an indication of the failureto connect to embedded device D (step 1014), e.g., in a manner analogousto that described above with reference to step 831 of FIG. 8C, butfurther including the indication of the failure to connect to embeddeddevice D. At admin device D, the admin application may transmit the newWAN IP address of embedded device C to embedded device D responsive tothe push notification (step 1031), e.g., in a manner analogous to thatdescribed above with reference to step 824. Embedded device D then mayconnect to embedded device C within the family cloud application basedon the new WAN IP address received from admin device D, and may send asuccess message to embedded device C (step 1022). The success messagepreferably includes the WAN IP address of embedded device D, so thatembedded devices C and D once again may have the correct WAN IP addressfor one another and may share digital information with one another,e.g., using the methods provided herein.

Alternatively, as noted above, methods based on DDNS may be used tomaintain communication between embedded devices C and D in the eventthat the WAP IP address of one or both of the embedded devices changes.Accordingly, the IP address update modules of each of embedded devices Cand D may be configured to maintain communication with each otherretrieving each others' new embedded device WAN IP address from adynamic domain name system (DDNS) server.

Sharing Embedded Device-Related Information

Although the foregoing embodiments primarily are described withreference to sharing digital information that originates from a mobiledevice or from an internal storage device or external storage devicecoupled to the embedded device, it should be understood that the digitalinformation alternatively may originate from the embedded device itself.One example of such information is a new WAN IP address that has beenassigned to the embedded device; when the embedded device determinesthat its WAN IP address has changed, it may push a notification of thenew WAN IP address to any mobile devices or other embedded devices thatare part of that embedded device's wireless cloud, e.g., as describedabove with reference to FIG. 10. Another example of such information isa new SSID for the embedded device; when the embedded device determinesthat has a new SSID, it may push a notification of the new SSID to anymobile devices that are part of that embedded device's wireless cloudand that communicate with the embedded device via Wi-Fi. Analogously,the memory of the embedded device may store one or more rules that causethe embedded device to send push notifications to admin or familydevices enrolled thereto under predefined circumstances. For example,the family cloud application of the embedded device may include a modulethat causes the embedded device to push a notification to the admindevice of that embedded device that includes a statistic of the embeddeddevice, such as if the load on the embedded device becomes too high orif there are too many devices connected to the embedded device. Based onthe push notification, the admin device may attempt to address thestatistic, for example by forcing a disconnection of a device that isusing too much bandwidth. Or, for example, the family cloud applicationof the embedded device may include a module that causes the embeddeddevice to push a notification to the admin device of that embeddeddevice that includes an indication that the embedded device wasattacked, such as if the embedded device detects greater than apredefined number of attempts to enroll in the family cloud. Based onthe push notification, the admin device may attempt to address theattack, e.g., by temporarily disabling the family cloud. Other suitabletypes, origins, and uses of digital information within the family cloudmay be envisioned.

Additionally, sharing digital information among mobile devices andembedded devices within a merged family cloud may provide furtherenhancements in user experience and functionality. For example, theadmin of a first family cloud may be particularly technically savvy,while the admin of a second cloud, merged with the first cloud, may notbe particularly savvy. If the admin of the second cloud encountersdifficulties—for example, receives an embedded device-relatednotification such as mentioned above—the embedded device generating thesecond cloud may permit the admin of the first cloud to access it so asto attempt to address the issue.

Loadable Application Components

As described above with reference to FIG. 1, certain embodiments of thepresent invention may permit executable modules or components associatedwith a new application, e.g., executable application components withinthe family cloud application of embedded device 110 or that areindependent of the family cloud application, to be dynamically loadedwithout requiring the software of the embedded device to be reloaded inits entirety or requiring the embedded device to be restarted. Inparticular, a new application for sharing information using the familycloud may include a first module or component that is executed on theembedded device, and a second and complementary module or component thatis executed on a mobile device. The various executable applicationcomponents on the embedded device preferably are configured to remain inan active state, so that they readily may interact with thecomplementary application components on the mobile device or otherembedded device on an as-needed basis. In comparison, as noted above,previously known embedded devices such as gateways may be configured toclose executable modules in the absence of detectable logicalinput/output devices.

Additionally, the various executable application components or moduleson the embedded device preferably are configured so as to permit thecomponents to be updated or replaced separately from one another—andindeed entirely new components to be added—without requiring refresh ofall of the software on the embedded device. For example, a softwaredeveloper may develop a new application configured to permit a new typeof digital information to be shared, and may make that applicationavailable on a web page or online application store for download to amobile device for free or for a fee. Alternatively, the developer mayprovide the application as an update to an existing softwareapplication. Such a new or updated application may have a component forexecution on the mobile device, and another component for execution onthe embedded device. The present embedded device preferably isconfigured so as to permit the embedded device component of the modulereadily to be loaded for execution on the embedded device. Such acomponent may be referred to herein as a “loadable module.”

The present embedded devices may receive and use such components orloadable modules in a variety of suitable ways. For example, FIG. 11Aillustrates a first illustrative method 1101 in which module componentis transmitted to the embedded device by a mobile device. Specifically,method 1101 begins on the mobile device side, at which a mobile deviceenrolled to the embedded device receives a new application, and theninstalls the mobile device component of that application (step 1111). Inthis embodiment, the mobile device receives the entire newapplication—that is, both the mobile device component and the embeddeddevice component of the application—but only installs the mobile devicecomponent. The mobile device then may connect to the embedded device,such as via an SSH connection, and may transmit the embedded devicecomponent of the new application to the embedded device (step 1112).Such connection and transmission may be made automatically responsive toinstallation of the mobile device component of the module, or may bemade at a later time, and optionally may be conditioned on user approvalof the transmission in a manner analogous to that described above;alternatively, the embedded device may detect the new application moduleon the mobile device, and may request the embedded device component ofthe module from the mobile device.

Then, on the embedded device side, within the new app module, theembedded device may receive and install the embedded device component ofthe new application from the mobile device (step 1121). Then, at themobile device, the mobile device component may be executed by theprocessor of the mobile device and may transmit first digitalinformation to the embedded device component (step 1113). At theembedded device, the embedded device component may be executed by theprocessor of the embedded device and may transmit second digitalinformation to the mobile device component (step 1122). Accordingly, theembedded device may load and utilize a new executable applicationcomponent, providing enhanced functionality, without the need for userintervention.

FIG. 11B illustrates an alternative illustrative method 1102 in whichthe embedded device downloads the embedded device component of the newapplication from the Internet. Specifically, method 1102 begins on themobile device side, at which a mobile device enrolled to the embeddeddevice receives and installs the mobile device component of a newapplication (step 1131). In this embodiment, the mobile device receivesonly its own component of the application. The mobile device then mayconnect to the embedded device, such as via an SSH connection (step1132). Such connection and transmission may be made automaticallyresponsive to installation of the mobile device component of the module,or may be made at a later time, and optionally may be conditioned onuser approval of the transmission in a manner analogous to thatdescribed above.

Then, on the embedded device side, within the new app module, theembedded device may detect the mobile device component of the newapplication (step 1141). For example, the new app module of the embeddeddevice may be configured to proactively determine upon connectionwhether the mobile device has any new application components, oralternatively the mobile device may be configured upon connection tonotify the embedded device of any new application components. Theembedded device then, within the new app module, may retrieve theembedded device component of the new application from the Internet andinstall that component (1142). Then, at the mobile device, the mobiledevice component may be executed by the processor of the mobile deviceand may transmit first digital information to the embedded devicecomponent (step 1133). At the embedded device, the embedded devicecomponent may be executed by the processor of the embedded device andmay transmit second digital information to the mobile device component(step 1143). Accordingly, the embedded device may load and utilize a newexecutable application component, providing enhanced functionality,without the need for user intervention.

Note that the use of such loadable modules need not necessarily be tiedto the use of a family cloud, and that any embedded device (including anembedded device that does not have a family cloud) may be configured soas to include loadable modules. For example, the application modulecomponents described above may be received and installed within theadmin or family application on the mobile device or within the familycloud application on the embedded device, or instead may be received andinstalled within any suitable program being executed on the respectivedevice or embedded device. Indeed, the embedded device may be configuredso as to obtain loadable modules at any suitable time from the Internet,and need not necessarily do so responsive to installation of mobiledevice components on a mobile device.
